This is OK in 8.5:
expect1.3> set a {1 2 3}
1 2 3
expect1.4> expr {[lindex $a 1] in {2 3 4}}
1
But not OK in 8.4:
expect1.8> set a {1 2 3}
1 2 3
expect1.10> expr {[lindex $a 1] in {2 3 4}}
syntax error in expression "[lindex $a 1] in {2 3 4}": extra tokens at end of expression
while compiling
"expr {[lindex $a 1] in {2 3 4}}"
Is there a way to make the expression backward compatible in 8.4?

improved since then), the truth is just that "in" was not there yet :D
An equivalent working in older Tcls:
expr {[lsearch -exact {2 3 4} [lindex $a 1]]>=0}
